- 個別の印刷媒体シートをそのスタックから分離して順次に給紙する給紙分離アセンブリであって、
少なくともひとつのベアリング用凹部を有するフレームと、
前記フレームによって担持される取り外し可能な印刷媒体トレイと、
前記取り外し可能な印刷媒体トレイに接続される分離装置と、
前記フレームに、前記取り外し可能な印刷媒体トレイに隣接させて取り外し可能に接続されるピックモジュールアセンブリであって、前記分離装置に隣接してニップを形成するピックローラと、前記少なくともひとつのベアリング用凹部に取り外し可能に受け入れられ、当該ピックモジュールアセンブリを前記フレームに取り外し可能に接続する少なくともひとつのフレキシブルベアリングと、を備えるピックモジュールアセンブリと、
を有し、
前記少なくとも1のベアリング用凹部は開口幅を有し、その開口幅は、第1の軸であって、前記少なくとも1のベアリング挿入用の前記少なくとも1のベアリング用凹部の開口幅に一列に並んでいる第1の軸に沿って、選択的に大きさが変化する前記少なくとも1のフレキシブルベアリングの自由状態での外径よりも小さく、かつ、前記少なくとも1のベアリング用凹部から前記少なくとも1のフレキシブルベアリングを取り外し可能であることを特徴とする給紙分離アセンブリ。 - 請求項1に記載の給紙分離アセンブリであって、
前記少なくともひとつのフレキシブルベアリングは、
(1)第一の軸に沿った可変の第一の寸法であって、当該第一の寸法が前記少なくともひとつのベアリング用凹部の開口幅と一列に並ぶとき、前記少なくともひとつのベアリング用凹部からの前記少なくともひとつのフレキシブルベアリングの取り外しを可能にする第1の寸法と、
(2)前記第一の軸に関して角度的にオフセットした第二の軸に沿った略一定の第二の寸法であって、当該第二の寸法が前記開口幅と一列に並ぶとき、前記少なくともひとつのベアリング用凹部からの前記少なくともひとつのフレキシブルベアリングの取り外しを防止する第2の寸法と、
